MYOG pack. How to attach shoulder straps? on 05/04/2010 08:51:21 MDT Print View

Thinking to make new pack. Golite ion style, very simple desing.

How to attach shoulder straps to bottom of pack? I read 5 yard to SUL article and i have new idea (maybe).

Pack is straight tube. Top closure is drawstring. Shoulder straps is sewed like the normal way in upped end.

Bottom is not round. It's like drybag closure with long webbing. See picture:
reppu

Is this good or bad idea?

Hey Timo,
I don't sew and haven't made a pack, but I think that's a pretty neat idea. It seems (to me) that it would simplify the hipbelt design. I'll be interested in what others think.

it seems to me that this idea would pull the webbing belt to the center of the bottom of the pack just like the top of a dry bag. I don't think it would be as comfortable as with the belt coming from the sides of the pack a few inches from the bottom.

That said, there's only 1 way to know anything for sure. Make a prototype.

My picture is bad, sorry.

Webbing is for shoulder straps. Not hip belt.

if no hip belt then this should be very easy to make and should work fine. Not sure it is any easier than making a square bottom like on a stuff sack but is worth a try.

Timo,
If you roll the bottom webbing and sew it, how will you get it to run through buckles?

Or are you dropping adjustability?

Shoulder straps is like normal backpack, only difference is attachment to pack bottom.

Got it.
Rolled at the bottom, flat at the buckle.

Sounds good.

Looks like extra webbing to me, which is the heaviest part of a ul pack.

I'm a gram weenie I suppose...total weight of my 2800 c.i. MYOG pack is 4.25oz. I think I could get it under 4oz though.

Would love to see some photos once you make your prototype!

I didn't mean to hijack your thread. I've been meaning to post info in the MYOG section, but haven't had a chance. Here's mine and my wife's packs on our recent PCT section A hike...PCT-A 069

Main body is 1.3oz silnylon. Outside pockets are 1.1oz nylon. Shoulder straps and hip belts (only wife's has hip belts) are 2.1oz nylon. Built like a large stuff sac, reinforced at pressure points. We have a couple hundred miles on them and still kicking!

About straps on 05/04/2010 13:49:20 MDT Print View

How about shoulder straps in upper end. In my desing there is no seam where i can sew shoulder straps. I going to sew straps middle of the fabric and i fear durability.

One way is glue and sew same fabric about 5x15" piece inside pack. Then sew shoulder straps middle of this piece. I think it's add durability, but is it enough? Material is normal lighweight silnylon.

Re: About straps on 05/04/2010 13:54:47 MDT Print View

Same here Timo. I sewed a 3.5" x 10" piece of 2.1oz nylon to the inside of the pack (didn't glue). Then I box stitched the shoulder straps to that area, then used three vertical bar-tacks across the area. The part that attaches to the pack is about 3" x 1", and I used a 1 1/4" seam allowance at the ends of the straps so they would be double thick. No signs of stress.

Timo,

Check out Jay Ham's article on sewing a SUL pack.

https://www.backpackinglight.com/cgi-bin/backpackinglight/process

Click on the link below and click on number 3., LAB 2300 cu. in. Pack, under the listing backpacks. Then click on construction, followed by a click on Padded shoulder strap assembly.

http://www.backpacking.net/makegear.html

There are plenty of pictures and instructions in both links. The second link also has instructions for a hip belt.

I hope this helps. :-)
